new Hamilton

[richard.ucci at att.net]

Hi list,
Tuned this new Hamilton grand at dealers just before Christmas. No big deal, not great ,but no real major problems. Went back last week after a prolonged cold snap here in the NE. 
Key dip was no more than 8mm and regulation was terribly off as you would expect.
Looked under fronts and found about an average of 8-10 punchings under each key,also key height is off on several naturals.
I'm open to any suggestions besides gasoline and a match to correct.
My first thought is to redo height and dip and then regulate,but could this be a key frame problem? Humidity level has not been over 30% in this room.
RU/UP
